CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 347,006, dated August10, 1886.

Application filed April 27, 1886.

To all whom it may concern:

Be it known that we, BENJAMIN J. MILES and MARTIN DUNNE, citizens of theUnited States, residing at Girard, in the county of Trumbull and Stateof Ohio, have invented a new and useful Improvement in Oar-Couplings, ofwhich the following is a specification, reference being had to theaccompanying drawings.

Our invention relates to an improvement in car-couplings; and itconsists in the peculiar construction and combination of devices thatwill be more fully set forth hereinafter, and particularly pointed outin the claims.

In the drawings, Figure 1 is a perspective view of our invention. Fig. 2is a vertical longitudinal sectional view of the same.

A represents a draw-head, in which is secured avertically-movable pin,B. The lower end of this pin is notched or grooved, as at O, and adaptedto engage with a countersunk opening, D, in the lowerside of thedraw-head, which is provided with a tongue or flange, (1, correspondingto the groove 0. On the upper side of the draw-head is a verticalguideway, E, the sides of which are inclined, forming a dovetailedtongue, 6, which fits a similar groove, 1), in the head of the pin. Onthe upper end of the guidewaysE is made ahorizontal groove or notch, e,and the upper end of the pin is provided with a loop or ring, F, whichis adapted to engage with the said opening or groove 6, and therebysupport the pin in a vertical position, as shown in dotted lines in Fig.2. To the lower end of the pin, and projecting from the front sidethereof, is socured a foot, G, the under outer end of which is roundedor inclined, as shown. This foot is dovetailed to the lower end of thepin, and is thereby made removable therefrom.

H represents the usual couplinglink.

The operation of our invention is as follows: \Vhen the coupling-linkenters the draw-head, it strikes the inclined or curved. side of theSerial No. 200,353. (No model.)

foot G, and raises the same and the pin, and the latter drops by its owngravity behind the link when the outer end of the latter reaches theinner end of the opening in the draw-head, thereby securely coupling thecars together. In order to uncouple the cars it is only necessary toraise the coupling-pin, and when it is desired that two cars should cometogether without coupling, the coupling is raised and supported in thatposition by engaging the ring or loop with the notch e on the upper endof the guideway.

By providing the countersunk opening in the under side of the drawheadfor the lower end of the coupling-pin, lateral strain on the said pin iswithstood, thus preventing the said pin from becoming bent.

Having thus described our invention, we claim-- 1. The combination, withthe draw head having the vertical guideway on its upper side, of thevertically-movable pin engaging the guideway and having the foot Gsecured to the pin by a dovetailed joint and projecting from the frontside of the pin, the lower side of the foot being rounded or inclined atits outer end, substantially as described.

2. The combination, with the drawhead having the vertical guideway onits upper side provided with the notch e, of the verticallymovablecoupling-pin having the head engaging with the guideway and providedwith the ring or link to engage with the opening e, and thereby securethe pin in a raised position, for the purpose set forth, substantiallyas described.

In testimony that we claim the foregoing as our own we have heretoaffixed our signatures in presence of two witnesses.
